Heart failure is a complex clinical condition that can arise from many different causes. Therefore, its treatment is based on the principle of identifying and eliminating the underlying cause. For example, in patients who develop heart failure due to blocked arteries, opening the blocked vessels is generally the most prioritized and effective initial treatment method. However, if the disease process has progressed and permanent damage has occurred in the heart, opening or replacing the blocked vessels may not fully restore the heart's functions or completely resolve the heart failure. In such cases, lifelong routine supportive treatments are required. The most important step in the treatment of congestive heart failure is always to apply treatment options directed at the specific cause.
